A 3 day treatment benefit was also observed in patients aged > 50 years purchase 100mcg ventolin fast delivery asthma definition qualitative, compared with 1 day in patients aged < 50 years cheap 100 mcg ventolin mastercard asthma treatment dosage. In ad- dition, zanamivir has been shown to be effective in patients at risk of developing influenza-related complications such as age ≥ 65 years and the presence of under- lying chronic disease including asthma, chronic obstructive pulmonary disease, cardiovascular disease, diabetes mellitus, and immunocompromise (Lalezari 2001). Influenza infections may lead to respiratory tract complications that result in antibi- otic treatment. A meta-analysis of 7 clinical trials reported that 17 % of placebo recipients developed a respiratory event leading to antibiotic use, mainly for acute bronchitis or acute sinusitis, whereas among zanamivir-treated patients the inci- dence of respiratory events leading to the use of antimicrobials was 11 % (Kaiser 2000b). In the setting of a large managed care plan (> 2,300 patients treated), the patterns of influenza compli- cations were found to be similar in zanamivir-treated and untreated patients (Cole 2002). Prophylaxis A series of randomised trials have proven the efficacy of zanamivir in the preven- tion of influenza. In a study involving healthy adults, 10 mg once a day or placebo was administered by oral inhalation at the start of the influenza outbreak. Zanamivir was 67 % efficacious in preventing clinical influenza (6 % [34/554] clinical influenza in the placebo group vs. Another clinical trial enrolled families with two to five members and at least one child who was five years of age or older. As soon as an influenza-like illness devel- oped in one family member, the family received either zanamivir (10 mg zanamivir inhaled once daily for 10 days) or placebo. In the zanamivir families, 4 % of fami- lies had at least one new influenza case, compared with 19 % in the placebo fami- Zanamivir 217 lies. A similar risk reduction was shown in a study where zanamivir was administered after close contact with an index case of influenza-like illness (Kaiser 2000). In a study of inhaled zanamivir for the prevention of influenza in families, 4 % of zanamivir versus 19 % of placebo households had at least 1 contact who developed symptomatic, laboratory-confirmed influenza (81 % protective efficacy). The pro- tective efficacy was similarly high for individuals (82 %) and against both influenza types A and B (78 % and 85 %, respectively, for households) (Monto 2002). Children In a trial on children aged five to twelve years, zanamivir reduced the median time to symptom alleviation by 1. Zanamivir-treated patients returned to normal activities significantly faster and took significantly fewer relief medications than placebo-treated patients (Hedrick 2000). Children, especially those under 8 years old, are usually unable to use the delivery system for inhaled zanamivir appropriately (not producing measurable inspiratory flow through the diskhaler or producing peak inspiratory flow rates below the 60 l/min considered optimal for the device). As a lack of measurable flow rate is related to inadequate or frankly undetectable serum concentrations, prescribers should carefully evaluate the ability of young children to use the delivery system when considering prescription of zanamivir. When zanamivir is prescribed for children, it should be used only under adult supervision and with attention to proper use of the delivery system (Relenza 2003). Special Situations Special settings in which zanamivir has been used include acute lymphoblastic leu- kemia (Maeda 2002) and allogeneic stem cell transplantation (Johny 2002). The second report found no toxicity attributable to zanamivir and rapid resolution of influenza symptoms. Avian Influenza Strains In a study performed on mice in 2000, zanamivir was shown to be efficacious in treating avian influenza viruses H9N2, H6N1, and H5N1 transmissible to mammals (Leneva 2001). To date, no virus resistant to zanamivir has been isolated from immunocompetent individuals after treatment. Known resistance mutations are both influenza virus subtype and drug specific (McKimm-Breschkin 2003). There is evidence for different patterns of susceptibility and cross-resistance be- tween neuraminidase inhibitors (Mishin 2005, Yen 2005), but no studies have so far evaluated the risk of emergence of cross-resistance in clinical practice. Zanamivir is not metabolised, and the potential for clinically rele- vant drug-drug interactions is low (Cass 1999b). There is no theo- retical basis for expecting metabolic interactions between zanamivir and other co- administered compounds (Daniel 1999). Each Relenza Rotadisk contains 4 double-foil blisters and each blister contains 5 mg of zanamivir (plus 20 mg of lactose which contains milk proteins). Here, a blister is pierced and zanamivir is dispersed into the air stream when the patient inhales through the mouthpiece. The amount of drug delivered to the respi- ratory tract depends on patient factors such as inspiratory flow. Patients should be instructed in the use of the delivery system, and instructions should include a demonstration – which may be difficult in daily medical practice. When prescribed for children, zanamivir should only be used under adult supervi- sion and instruction.
